IMPROVEMENT IN SINGLE HARNESS.`

To ALL wHoM IT MAY o oNcERN:

Be it known that I, ORLANDO V. FLORA, of Madison, in the county ofJefferson, and Sta-te of Indiana, have invented ncwnandusefulrIrnprovements in Single Harness; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable those skilled in the art to maker-'1nd use the same, refer. encebeing had to the accompanying drawings forming part of thisspecification.

This invention relates `to a. new mode of attaching single harness tothetlrillsY of a vehicle, and releasing it therefrom in a rapid, simple,and effective manner; also, making the attachment to the thills atorne-ar thelpoint where the hold-back strap is usually fastened, thusgetting two bearings on the thills, viz ,one at the fastenings, theother at the thll-bearers. I

The accompanying drawings illustrate my invention.

Figure 1 is aside elevation of a horse and carriage, to show the placeof attachment of the harness to the thills.

Figure 2 is a side elevation of thc sp'ri11gdraught4 bolt, attached inits proper place on the shaft, drawn full size. v

Figure 3 is an end `elevation of the same. l

Figure 4 is an elevation of the draught-plate, with the straps attached,drawn full size.

A, in the drawings, is the shaft or thill.

B is the spring-case, secured to the under side of the thill by means ofscrews through the flanges on the ends of the case.

C is a bolt, withv a T-shaped head, attached to one cndof the rod D, andat a right angle thereto. The rod D passes through and has a bearinginthe 'end of the case Around this rod is coiled a. strong spiral spring,a a a, one end of which abuts against the bol'tC, andthe other againstthe forward end of the case B.

The rod D has'a movement in the direction of i'ts length,l this movementcompressing the spring just so fait as the length of the slot inthespring-case will admit, the bolt C actingas a stop, to preve'nt thespring being compressed too much.' i

The movement of the bolt C in the-slotand the operation of the coiledspring a a a, are intended tocompensate for the alternate motion of thellorsesshoulders when walking, and to prevent his b'eing injured bysudden jars or jolts.

E, fig. 4, is a plate, of metal, with n slight lateral curvature.` Inthe rear end of this plate-is a curved slot, by

which to attach V'theholddmck strap G, and in the forward end a straightone, by which to attach the draughtstrap or trace F.

In the centre of the plate E is a circular opening, of suilicientdiameter to admit the shank of the bolt C, (gs. 2 and 3,) easily.Branching from this .circular opening is n. rectangular one, which issomewhat broader and deeper than a single branch ofthe T-head of theboltC. This opening projects forward at an anglo of aboutfortyifivedegrees. v i

The dotted lines show the position ofthe bolt C, when the harness isattached to the thills of a vehicle.

The operation of my invention is as follows:

The draught-strap or trace Fis secured to the forward end of the plateE,-as shown, and the hold-back strap G to the rear end of the same; theother end of thisstrap passing through the breeching-ring, as shown iniig. 1, and properly adjusted by the buckle.

The rear slot in the plat-e E is curved, to admit of such verticaladjustment as may be desired. y

The spring-draught bolt, (figs. 2 and 3,)'is fastened securely to theunder side of the thill at the proper point, by means of screws or otherdevice, so that the bolt C projects inward toward the horse.

When'it is desired to attach the horse to the Avehicle,thc thills are,passed through the thill-bearers, the plate E is turned until therectangular' openingcoincides with the head of the bolt C, the bolt ispassed through and the plate turns back to its natural position, thuslmaking a firm and reliable fastening.

A. similar operation releases the harness from the vehicle. Havingthusdescribed my invention, what I claim as new, and desire to secuie by`Letters Patent, is 1.l So arranging the circlar openingin thedraught-'plate E, with al no teh, extending forward at an angle of aboutforty-five degrees, that the dreught-bolt C may be p assed through byxjo't'atng the plate vertically, and, when passed through, will fom a.fasteningfor the purpose and in the manner as set forth.

2. -Placing the draught-plate E at or near the point where the hold-beckstrap is usually fastened, so as to allow an elssfe bearing et thatpoint en the shaft, while the other bearing oftheshaft is arranged inthe'usual manner, forV the purposes as described. t Nv ORLA DO V. FLORA.
